TIL E-MOLDING MACHINE.

Application filed June 23, 1921. Serial No. 479,889.

T all whom it may concern Be it known that I, BYRON L. BACOT, a citizen'of the United States, residing at Mo- Comb, in the county of Pike and State of Mississippi, have invented new and useful Improvements in Tile-Molding Machines,

of which the following is a specification.

This invention relates to machines for molding. roofing tiles, and its object is to provide a very simple and efficient machine of this kind, and also one which is rapid in operation.

The invention also has for its object to provide a machine for" forming the tile with depending bottom lugs. I I

The objects stated are attained by means of anovel combination and arrangement of parts to :be hereinafter described and claimed, and in" order that the same maybe better understood, reference is bad to the accompanying drawings forming a part of this specification.

I In the drawings,

Figure 1 is a side elevation of the machine;

Fig; 2 is a plan view thereof;

Fig. 3 is a cros -section on the line 83 of Fig. 2;

F'g. 4 is an enlarged cross-section on the line 4% of Fig. 2 showing the mold filled;

Fig. 5 is a plan view minus a pallet, and

Fig. 6 is a 'crosssection on the line 66 of Fig. 5.

Referring specifically to the drawings, 10 denotes a pallet on which is placed the cement or analogous material employed in the construction of the tile, said pallet being shaped to give the tile the desired shape on one side. The other side of the tile is shaped by a forming tool 11 which is placed transversely of the mass of cement on the pallet and run across the'mass to compress and shape the same. The cement or other materialis shown at 12. The machine is designed more particularly for molding a roofing tile which is rectangular in outline and corrugated or fluted to form ridges and depressions running from the top to the bottom. The tile, on its under side, a short distance from the edge which is at the bottom when the tile is laid, is also to have two laterally spaced securing lugs as shown at 12 in Fig. 4., which lugs are somewhat hook-shaped, the hooks being outwardly or laterally presented, for engagement by the nails whereby the tile is secured in place on the roof.

The supporting frame of the pallet 10 is a rectangular box-like member having front and rear end walls 13 and 14', and side walls 15. The front end wall 13 is not as high as the other walls and it is provided with a hlnged extension 16 rising to the height of the latter and forming an end gate which seats between the side walls 15. The'hinge of the end gate 16 is shown'at 17, and at 18 is shown a lever for operating said gate, said leveg being pivoted to the wall 13 as shown at The frame hereinbefore described is supported by legs 19 suitably braced by intermediate and bottom cross bars 20 and 21 at the sides, and inside the frame are front and rear supporting strips 22 and 23 for the pallet 10. The frame also carries corner blocks 24-through which are threaded vertical screw stems 25 which support the strips 22 and 23 at their upper ends. It will therefore be seen that the pallet-supporting strips are vertically adjustable so that the pallet may be properly positioned relative to the top edges of the walls 14- and 15 and the end gate 16, according to the desired thickness of the tile to be made.

The following means are provided for mlolding the hook-shaped lugs 12 of the ti e Near the front end of the pallet 10, the

Specification of Letters Patent. Pafient ed' June 13 1922;

latter has two laterally spaced apertures 26,

and on the bottom of the pallet, at the side of each aperture is a lug 27. In the front face of the lug 27 is a cavity 28 which is in direct alinement with the aperture 26, and hence the material on the pallet can pass through said aperture into the cavity to fill the same, the cavity conforming in shape to thle shape of the lug 12 to be formed on the ti e.

; The cavities 28 of the lugs 27 are open in front and also on one side, and hence some retaining means for the material: must be provided, which means will now be described.

Carried by supports 29 on the walls 15, is a transverseshaft 30 which is stationary and pivotally supports two plates 31 and 32 which face each other. The plate 31 has hinge arms 31 and the plate 82 has hinge arms 32, the same being journaled on the shaft 30. On that side of the plate 32 which is opposite and facing the plate 31: are two pairs of lugs, adapted to co-operate with the lugs 27 the members of said pairs of lugs being indicated by the reference numerals 33 and 34:. The lugs 33 are positioned to come alongside the inner sides of the lugs 27, and the lugs 34 to come along the outer sides of said lugs 27 through which the cavities 28 open, so as to close up the latter, as clearly shown in Fig. 4;. The plate 31 is de signed to be swung against the front face of the lugs 27 to close up the cavities 28 in front.

The cavities 28 are closed up at the side and in front in the manner described by swinging the plates 31 and 32 toward each other, this operation being simultaneously effected by a lever 35 having actuated connections withthe plates. The lever 35 is on a rock-shaft 36 supported by the crossbars 9.1 and provided with a rocker arm 37. Two angle or bell-crank levers 38 and 39 are pivotally connected as shown at 40; One arm of the angle lever 38 is connected to an arm 41 extending from the plate 31, and the other arm of said lever is connected by a link 42 to the rocker arm 37. One arm of the angle lever 39 is connected to an arm 43 extending from the plate 32, and the other arm of said lever is connected by a link 4E4: to the rocker arm 37. The operating lever 35 works in a guide 45 carrying a suitable spring latch device 46 for locking said lever when it hasbeen swung to place the plates 31 and 32 in operative position.

In operation, the pallet 10 being in place, and the plates 31 and 32 having been swung toward each other to close up the cavities 28, as hereinbefore described, the cement or analogous material is placed on the pallet to a height slightly above the plane of the top edges of the side walls 15. The forming tool 11 is now placed transversely of the material and run over the same from the rear to the front, it being seated on the top edges of the side walls 15 to be guided thereby. The forming tool compacts the cement or other material and also shapes the top surface and the longitudinal or side edges of the tile, the bottom surface being shaped by the pallet itself, and the lugs 12 being molded by the cavities 28. The finished tile, with the pallet, is readily removed from the machine upon swinging the end gate down, after operating the le er 35 to spread the plates 31 and 32 and thereby take the plate 31 and the lugs and 34; clear of the lugs 27 on the bottom of the pallet. The tops of the rear end wall, 14. and of the front end gate 16 are ridged to conform to the ridged contour of the bottom of the forming tool, and the top edges of the side walls 15 have guide grooves a7 for guide lugs 48 on the bottom of the fcrming tool 11. The end wall 141 and the end gate 16 rise slightly above the pallet to form the ends of the tile and the guide grooves 47 are continued therethrough, as shown in Figs. 2 and 5, in order 1,4,1e,1es

that the forming tool may he slid over said wall and end gate and be carried along the entire length of the pallet. The front end of the pallet has a small top recess 49 to mold a transverse rib on the bottom of the tile at this end. The pallet and the forming tool are also shaped to produce in the finished tile a longitudinal rib 12 adjacent to one edge, and a similar groove 12 adjacent to the other edge. When the tiles are assembled on the roof the rib of one tile seats in the groove of the adjacent tile in the row.

I claim:
